Question:

What is the GPM capacity for 2 Type L copper piping?

What is the source of your answer? Isn‘t there a chart that shows normal or nominal flow capacties somewhere?

Answer:

No, you will be fine with that. Maybe you should try and just take her out of the car seat to take her up to your apartment. See if that helps. A baby really just shouldn't be exposed to too many things when just being born because they are so prone to catching things. As far as you, I also had a C-section and I know for me I went walking at the mall because my baby was born around Christmas time and we had pics taken and needed to do last min. shopping and it caused me to have really bad blood clots coming out. You don't have to stay in your home all the time but just from experience just do the hard things you have to but if you have a choice just take it easy. at least for another week. Good luck!
i feel your pain is it anyone that can help you out for about a week or so like a parent, sibling or friend? because i had my first child by c section 3 months ago and it was rough for about a week and a half. maybe it will help if you only took her out of the car seat instead of both her and the seat because you are not supposed to lift anything heavier than your baby. get a carrier that goes on the front of you so you won't be actually carrying her also a swing
161 gpm or .0215 cu ft per min. assuming the flow is 1 foot per minute. at any other velocity multiply thw number by the velocity in FPM
if you can afford type 'L' and plan on keeping the home forever and passing it on to your kids, then do it. if you are going to ever sell the home then go for type 'M'. Use 'L' if you have a recirculating system, and be sure to ream your cuts. Type 'M' will last just fine in a residential setting. even PEX will work fine. any piping installed properly will last decades. even galvanized steel pipes will last 50+ years.
Bell and Gossett has developed a really nice device that they call a System Syzer Calculator. It's just a round nomograph that will provide information on delta P, length, gpm, Cv, ft of head, and velocity. To answer your capacity question, the 'normal' range for 2 L copper is from 18 to 46 gpm. That's based on friction losses of .8 to 4.5 psi per 100 feet. That will also give you a velocity range of 8 to 47 feet per minute.
